Uninstalled 77.77 drivers and now XP won't correctly ID my card !!

Hi,

I've just installed XP SP2 on system with a GeForce 2 400MX AGP card
in it. On the install, XP correctly recognised the card and used it's
own drivers. Later, I tried the latest Nvidia drivers (77.77) and
found them to be a little sluggish in comparison. So, wanting to
return to the original XP ones, I uninstalled the Nvidia drivers via
control panel. On the reboot, XP detected the video card as a "Video
Controller (VGA Compatible)" and *not* as an "NVidia Geforce 2 MX 400"
(which it did on the install).

No matter what I do, I cannot get XP to recognise the card properly
again, nor install any drivers for it. I can however reinstall the
Nvidia ones and it is once again correctly seen as a Geforce 2 MX 400.

Remove them, and I'm back to "vga compatible" !!

I've tried 'sfc /scannow' to restore any critical files, but no joy.

If I tell it to automatically install drivers for it, it says it can't
find any, and likewise if I try manually ("I will choose the driver to
install") once I choose Display Adapters in the category list, it says
"no drivers are available" (or something to that effect).

It's driving me nuts !!!!

PLEASE !!! - Can someone help ? !! I'm presuming that the uninstall
of the Nvidia drivers took something with them that XP uses to
identify the card, but I don't know what !!

Cheers,

Kev.
